A restaurant is building an outside seating area. The owner created a map with the coordinates A ( -11, 11 ), B ( -3, 11 ), C ( -3,1), and D ( -11,1 ). Each unit on the coordinates plane represents 1 foot. solve to find out how many feet of wall material they will need to build the new area (the perimeter). A 40 feet. B 52 feet. C 80 feet. D 36 feet.

To find the perimeter of the seating area, we need to add up the lengths of all four sides.

The distance between points A and B is 8 feet (|-11 - (-3)| = 8).

The distance between points B and C is 10 feet (|11 - 1| = 10).

The distance between points C and D is 8 feet (|-3 - (-11)| = 8).

The distance between points D and A is 10 feet (|11 - 1| = 10).

Adding up all four sides, we get:

8 + 10 + 8 + 10 = 36

Therefore, the restaurant owner will need 36 feet of wall material to build the new seating area. Answer: D 36 feet.
